ELECTRIC BELT AND APPLIANCES THEREFOR.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application led January '7,1907l Serial No. 351,039.

To all whom it may conccm:

Be it known that I, MICHAEL HATZENBUEHLER, a citizen of the UnitedStates, residing at Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in ElectricBelts and Appliances Therefor, of which the following is aspecification.

My invention relates to improvements in electric belts and appliancestherefor, and has for its salient pliance in which the regulation ofvoltage is accoIn-' plished by cutting in or out of circuit, by a simplemeans, more or less of the current producing batteries. And yet anotherobject of my invention is to provide an improved battery for applicationto an electric belt.

Other and further objects of my invention will become apparent to thoseskilled in the art from the folv lowing description taken in conjunctionwith the accompanying drawing, wherein;

Figure 1 is an elevation of a belt embodying my invention; Fig. 2 is arear elevation with parts of the lining broken away; Fig. 3 is atransverse section through the battery cell on its broader dimensions,and on line 3-3 of Fig. 4. Fig. 4 is a section on line 4 4 of Fig. 3.

Throughout the drawing like numerals of reference refer always'to'likeparts.

Referring now to the drawing, 5 indicates in general a supportingstructure, such as a wide, padded portion of a belt,'or other appliance,adapted to be worn upon the body of the user, and preferably composed ofa stiffening or backing sheet 6, of canvas or other suitable relativelyheavy material, suitably covered on its front face for artisticappearance, and on its rear face covered with a padding sheet 7, looselyapplied so thatpthe necessary wiring for the appliance may be runbetween the stiffening sheet 6 and the padding sheet 7.

Upon the front of the supporting structure 5 are applied a plurality ofbatteries, each preferably con- Y/'stru'cted as illustrated in Figs. 3and 4, that is to say,

suitably sealed in the casing. The two or three cells may be of paper orother suitable insulating material, surrounding the battery cells andprovided at its ends with removable metal caps 14 and 14. Suitablewiring I is provided for connecting the several cells 9 in series, oneterminal wire being led to and connected with cap 14, and the otherterminal wire led to and connected with cap 14 so that the two said capsform terminal connections for the battery units, each comprising severalcells. l.

15 and 15 indicate metal clips permanently secured to the respectivecaps 14, 14 in alining position, as by small bolts fixed by solderbodies, and to which may also be conveniently connected the terminalwires for the series of cells. The free ends of the clips are bent atright angles to the attached parts thereof, to lie in a common plane inalinement with a side of the battery envelop, and are suitablyperforated to receive studs 16, 16, permanently attached to thestiffening piece 6 and threaded to receive thumb nuts 17, by whichtheclips, and consequently the battery rigidly attached thereto, may bedetachably positioned in place upon the belt proper.

It will be observed that the structure thus described is symmetrical inthe arrangement of its attaching means so that it may be applied witheither terminal 14 or 14 in engagement with either permanent stud, 16 or16 and may readily be reversed in position without disturbing the studs16 or the wiring connected to the electrodes, as hereafter described.

Upon a suitable point on the belt I provide a circuit controller 20,comprising a movable arm 2l and a series of contact points 22 in numberpreferably one greater than the number of current producing units orbatteries upon the belt. The movable arm 21 of this controller isconnected by suitable conductors 23 and 24 with a terminal plate 24 uponone end of the belt pad, and to such terminal are connected a pair ofbody electrodes 25. Y L

26 indicates the opposite terminal plate to which are connected the bodyelectrodes 27.

The wiring for the batteries is preferably arranged as follows: Fromterminal plate 26 connection is made with the post 16 to which the.nearest battery is connected, and from the opposite post 16 connectionis made through the post 16 of the next battery to the first activecontact point of the switch 20; from the post 16 of said second batteryconnection is made to post 16 of the next battery and thence to thesecond active contact of the switch, and so on throughout the totalnumber of batteries employed. Thus it will be observed that when the arm21 of the switch is thrown to the rst contact, current passes from thefirst battery alone through the switch to terminal 24, thence throughthe electrodes 25, the body of the wearer, the electrodes 27 and plate26 back to the opposite terminal of said single battery. If the switchbe moved a point is neediul only to reverse the batteries withoutdisturbing the connections in any way.

For covering the batteries I preferably provide upon the belt a flap 30,which may be fastened in closed position by means ol snap buttons 3l orany other approved lashion.

Having thus described my invention, What l claim and desire to secure byLetters Patent, oi the United States, is:

1. In an electric belt, studs permanently secured to said belt andadapted to form part of the electric circuit thereof,'a battery havingterminal clips permanently secured thereto and connected with thebattery terminal,

said clips being symmetrically disposed and arranged eachl forconnection with either of the studs whereby the batA tery may bereversed relative to the permanent studs.

2. In an electric belt, body electrodes, studs permanently applied tosaid belt, and adapted for inclusion in the circuit with said electrode,and a battery adapted for connection with said studs comprising current.producing means, a casing therefor having metallic end pieces insulatedfrom each other and respectively connected to the terminals of thecurrent producing means, and clips secured to said metallic caps,adapted for detachable con nection with the studs upon the belt.

3. In a device of the character described, a supporting body, studssecured thereto, adapted for inclusion in an electric circuit, a batteryfor connection with said studs comprising a current producing means, acasing therefor having an electrically non-conducting mid-portion andelectrically conducting end pieces, clips permanently scA cured to saidend pieces and adapted to engage the per marient studs upon thesupporting structure, said clips and studs being symmetrically arranged,whereby the hat tery may be reversed upon the studs.

l. In a device of the character described, a supporting structure, studsthereon, a battery comprising a plurality ot current producing cellselectrically connected, an en velop for said plurality of cells,comprising an insulated mid-portion and electrically conducting caps,said caps being connected with the cells i'or inclusion in the electriccircuit, and clips permanently secured to said caps adapted forconnection with the studs upon tlic supportY ing structure.

In testimony whereof l hereunto set my hand in the presence of twowitnesses.
